A cumulative change of less than 2°C by the end of this century will do no net harm. It will actually do net good [...] rainfall will increase slightly, growing seasons will lengthen, Greenland's ice cap will melt only very slowly, and so on.

Note even Jonathan Swift would dare to write a satire in which politicians argued that - in a world where species are vanishing and more than a billion people are barely able to afford to eat - it would somehow be good for the planet to clear rain-forests to grow palm oil, or give up food-crop land to grow biofuels, solely so that people could burn fuel derived from carbohydrate rather than hydrocarbons in their cars, thus driving up the price of food for the poor.
